Efficacy of cocoa husk biofertilizer

24/09/2025 Go to Evidence

This study evaluates the effect of a liquid biofertilizer made from cocoa husks on the growth and chlorophyll content of sweet pepper plants (Capsicum chinense) in San Martín, Peru. The results show significant increases in height, stem diameter, and chlorophyll content, especially with doses of 1250–3000 mL, demonstrating its potential as a sustainable input to improve the physiological performance and early growth of the crop (Solórzano et al., 2025).

Bioferments improve cocoa growth

07/09/2025 Go to Evidence

This study evaluates the effect of different bio-ferments on the morphology and quality of cacao (Theobroma cacao L.) seedlings under nursery conditions. Treatments were compared based on parameters such as height, stem diameter, number of leaves, and seedling quality. The results show significant improvements in growth when bio-ferments are applied, highlighting their potential as an agroecological input for early stages of cacao development (Chuquizuta et al., 2025).

Wild camu camu shows high useful variability

07/08/2025 Go to Evidence

This study phenotypically characterizes 74 wild accessions of Myrciaria dubia (camu camu) from the INIA ex situ germplasm bank to identify variability relevant for genetic improvement, conservation, and sustainable use programs. Morphological, physical, and fruit quality characteristics were evaluated, revealing a wide diversity that can be used to select genotypes with higher yield and quality Imán (Correa et al., 2025).
